Specification of Letters Patent.

Patented Aug. 10, 1915.

To all whom it may concern; j

Be it known that I, LEONARD R. OAKLEY, a subject of His Majesty the King of Great Britain, and a resident of Waterbury, in the county of New. Haven and State of Connecticut, have made and invented certain new and useful Improvements in Tacks, of which the following is a specification.

My invention relates to an improvement in tacks, and more particularly to that kind or type thereof used or employed in connection with buttons, or like articles, for the purpose of attaching the latter to cloth or fabric. v

In the manufacture of tacks, having a cap stamped around the head and bent to'fin'ally cover the same, it, has heretofore usually resulted in the head being rough and irregular, due to the metal folding upon itself.

An object of this invention is todo away with the foregoing disadvantages and also to provide a tack wherein the capped head is solid to all practical purposes with the shank of the tack.

invention consists in certain novel features of construction and combinations of parts 5 as will be hereinafter fully describedand pointed out in the claim.

In the accompanying drawings, Figure 1 is a view of the cap blank; Fig. 2 is a perispective view of the same after being drawn up into the form of a shell, and Fig. 3 a sectional view of the same; Fig. 4 is a view in perspective showing the shell partially closed over the head of the tack, and-Fig. 5 a sectional view of the same. Fig. 6 is a view in elevation of the finished tack, and Fig. 7 a view of the same partly in elevation and partly in section; Fig. 8 is a plan view of the finished tack, looking at the underside of the capped head.

By reference to these drawings 1t willbe seen that my improved tack is made up of the ordinary tack of commerce, that is, a

tack comprising a sharpened or pointed shank A, and having the ordinary head B formed integral, therewith. In capping this head, I first form "a square blank C, Fig. 1, which 'by means of suitable (hes, (not shown), is cupped or drawn up into the form of a shell D provided with four points D, these pointed ends correspond ng with the four corners ofthe square-blank.

In the formation of this shell, it will be seen by reference to Fig. 2, that there is formed a circular wall or flange D surrounding the closed end D thereof, and

from which wall or flange extends the four points, the diameter of the shell being considerably larger than the head ofthe tack to be capped, as illustrated in Figs. 5 and 7. Within this shell is'placed the head of the tack, the circular wall D of the shell being subsequently bent inwardly and downwardly upon the under side or surface of the tack head B, this operation resulting in bringingthe edges of the pointedends together, as illustrated in Fig. 8, the extreme pointed ends .being somewhat flattened against the shank A of'the tack. In the 1 resulting article, there is therefore no crimping, bending, or folding of the metal N of the cap over'and upon itself.

By reference to Fig. 8 of the drawings it will be seen that the circular wallD of the shell D when folded inwardly upon the under side of the tack head, extends from the outer edge of the cap to approximately the outer edge of the head B formed intea of the pointed ends D, and which originally formed the edges a of the blank, abuttlng against each other on a line running or extending from the circular wall tothe I bend inwardly the metal of the cap on,

its under side around the outer edge of the tack head, the resulting article showing a circular groove E, as illustrated in Fig. 7

of the drawings.

From the foregoing it will be seen that my improved tack will be smooth, regular,

gral with the shank A. of the tack, the edges 7 and neatly capped, that it can be easily and economically manufactured, and that no loss or scrap results.

What I claim is An article of the class described, comprising a tack including a head and shank, a cap, the central portion of which contacts with the outer face of said tack head, triangular corners of said cap extending across the inner or opposite face of said head and impinging against the said shank, said cor- Y Q t e a 1,149,183
